### Core Functionalities

* Load and display experiment image data, including its various regions, markers and z-slices
* Provide an interface for hierarchical biaxial gating and KNN/FLANN clustering
* Allow for versatile population management to combine and re-cluster cell populations
* Visualize populations on region images and marker expressions in an intuitive heatmap
* Generate voronoi diagram for visualization and computation of neighboring populations
* Import and export annotated populations and analysis states
